How to Fix GHSA-9hpw-r23r-xgm5

To remediate this vulnerability, upgrade all affected Thread local dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

thread_local fixed: 1.1.4 
Upgrade thread_local to 1.1.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for thread_local

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9hpw-r23r-xgm5, inspect your project dependencies for Thread local:

inspect dependencies for thread_local

Analyze the terminal output to locate any version of Thread local in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Thread local, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the affected version of this crate, `{Iter, IterMut}::next` used a weaker memory ordering when loading values than what was required, exposing a potential data race when iterating over a `ThreadLocal`'s values. Crates using `Iter::next`, or `IterMut::next` are affected by this issue.
